Australia's Brody Ninyette has recorded a round of 67 to open up a slender lead going into the final day of the Perth International.
The world number 1019 carded seven birdies to seize the advantage in his home tournament and was joined at the top of the leaderboard by compatriot Brett Rumford.
Rumford shot a seven-under-par round of 65 to head a group of three players one shot adrift of Ninyette, with JB Hansen and Jeong Jin also in contention.
Ross Fisher produced a solid 71 to ensure that he remains just two shots behind the leader, while Danny Willett and Michael Hoey sit just behind the Englishman.
